Sildenafil, the active ingredient in Viagra, treats pulmonary hypertension (PH) by relaxing blood vessels in the lungs. This improves blood flow and reduces strain on the heart.
Specifically, sildenafil inhibits phosphodiesterase-5 (PDE5), an enzyme that breaks down cyclic GMP. Increased cyclic GMP levels lead to vasodilation.
Dosage for pulmonary hypertension varies significantly depending on individual patient needs and response. A physician will determine the correct dosage. Self-medication is dangerous.
Important Note: While sildenafil is FDA-approved for PH, it’s not a first-line treatment for all PH types. Doctors consider various factors–patient health, PH severity, and other medications–before prescribing it.
Potential Side Effects: Common side effects include headaches, flushing, and nasal congestion. Rare but serious side effects exist; prompt medical attention is necessary if these occur.
Patient Interaction: Open communication with your doctor is critical. Discuss any existing health conditions, current medications, and any concerns about sildenafil use. This ensures safe and effective treatment.
